Ahmedijimbob's obsession with all things nuclear is nothing but an attempt to divert the attention away from the pressing needs of it's young and growing population. The mullahs are experts at ramming such irrelevant drivel down the throat of a population that is seeing Iran's oil wealth being squandered on adventurism (like in Lebanon recently) rather than development.
Whenever an earthquake occurs in Iran hundreds of thousands of people die in an instant. Why doesn't Ahmedijimbob develop technology that will reduce such deaths to the hundreds or thousands? Such technology is freely available in the West/Japan and they will be more than willing to provide it to Iran.
But, of course, that isn't as sexy as developing nuclear energy for a non-existent reason and, even better, thumbing his crooked nose at the U.S.
